Abstract

The therapeutic system of the preferred embodiments includes a foot platform having a lateral segment and a medial segment. The foot platform is coupled to the foot of the patient and supports the body force of the patient. The foot platform functions to move the foot from an equilibrium position to an activated position. The transition of the foot between equilibrium position and activated position, preferably occurs substantially instantaneously once the foot platform supports greater than substantially half of the body force.

Claims (50)

1. A footwear product, comprising:

a first foot platform having a rear portion for supporting a heel of a foot, and a front portion for support a front part of the foot;

wherein the rear portion has a lateral segment and a medial segment, and the front portion has a lateral segment and a medial segment;

wherein the lateral segment of the rear portion has a first stiffness, the medial segment of the rear portion has a second stiffness, and the first stiffness is greater than the second stiffness; and

wherein the lateral segment of the rear portion with the first stiffness comprises a material that extends to the front portion.

2. The footwear product of claim 1 , wherein the lateral segment of the front portion is stiffer than the medial segment of the front portion.

3. The footwear product of claim 1 , wherein the first stiffness is at least 10% greater than the second stiffness.

4. The footwear product of claim 1 , wherein the medial segment of the rear portion abuts against the lateral segment of the rear portion.

5. The footwear product of claim 4 , wherein the medial segment of the rear portion is secured to the lateral segment of the rear portion.

6. The footwear product of claim 1 , wherein:

the lateral segment of the rear portion has a tilted configuration when a force imposed on the first foot platform exceeds a threshold; and

the lateral segment of the rear portion has a configuration that is less tilted relative to the tilted configuration when the force imposed on the first foot platform is equal to or below the threshold.

7. The footwear product of claim 1 , further comprising:

a second foot platform having a rear portion for supporting a heel of an additional foot, and a front portion for support a front part of the additional foot;

wherein the rear portion of the second foot platform has a lateral segment and a medial segment, and the front portion of the second foot platform has a lateral segment and a medial segment; and

wherein the lateral segment of the rear portion of the second foot platform is stiffer than the medial segment of the rear portion of the second foot platform.

8. A footwear product, comprising:

a first foot platform having a rear portion for supporting a heel of a foot, and a front portion for support a front part of the foot;

wherein the rear portion has a lateral segment and a medial segment, and the front portion has a lateral segment and a medial segment;

wherein the lateral segment of the rear portion has a first stiffness, the medial segment of the rear portion has a second stiffness, and the first stiffness is greater than the second stiffness; and

wherein the medial segment of the rear portion with the second stiffness comprises a material that extends to the front portion.

9. A footwear product, comprising:

a first foot platform having a rear portion for supporting a heel of a foot, and a front portion for support a front part of the foot;

wherein the rear portion has a lateral segment and a medial segment, and the front portion has a lateral segment and a medial segment;

wherein the lateral segment of the rear portion has a first stiffness, the medial segment of the rear portion has a second stiffness, and the first stiffness is greater than the second stiffness; and

wherein the lateral segment of the front portion is stiffer than the medial segment of the front portion.

10. The footwear product of claim 9 , wherein the lateral segment of the rear portion comprises a first material, the medial segment of the rear portion comprises a second material, and the first material at the lateral segment of the rear portion is stiffer than the second material at the medial segment of the rear portion.

11. A footwear product, comprising:

a first foot platform having a rear portion for supporting a heel of a foot, and a front portion for support a front part of the foot;

wherein the rear portion has a lateral segment and a medial segment, and the front portion has a lateral segment and a medial segment;

wherein the lateral segment of the front portion has a first stiffness, the medial segment of the front portion has a second stiffness, and the first stiffness is greater than the second stiffness; and

wherein the lateral segment of the rear portion is stiffer than the medial segment of the rear portion.

12. The footwear product of claim 11 , wherein the medial segment of the front portion with the second stiffness comprises a material that extends to the rear portion.

13. The footwear product of claim 11 , wherein the lateral segment of the front portion comprises a first material, the medial segment of the front portion comprises a second material, and the first material at the lateral segment of the front portion is stiffer than the second material at the medial segment of the front portion.

14. The footwear product of claim 11 , wherein the first stiffness is at least 10% greater than the second stiffness.

15. The footwear product of claim 11 , wherein the medial segment of the front portion abuts against the lateral segment of the front portion.

16. The footwear product of claim 15 , wherein the medial segment of the front portion is secured to the lateral segment of the front portion.

17. The footwear product of claim 11 , wherein:

the lateral segment of the front portion has a tilted configuration when a force imposed on the first foot platform exceeds a threshold; and

the lateral segment of the front portion has a configuration that is less tilted relative to the tilted configuration when the force imposed on the first foot platform is equal to or below the threshold.

18. The footwear product of claim 11 , further comprising:

a second foot platform having a rear portion for supporting a heel of an additional foot, and a front portion for support a front part of the additional foot;

wherein the rear portion of the second foot platform has a lateral segment and a medial segment, and the front portion of the second foot platform has a lateral segment and a medial segment; and

wherein the lateral segment of the front portion of the second foot platform is stiffer than the medial segment of the front portion of the second foot platform.

19. A footwear product, comprising:

a first foot platform having a rear portion for supporting a heel of a foot, and a front portion for support a front part of the foot;

wherein the rear portion has a lateral segment and a medial segment, and the front portion has a lateral segment and a medial segment;

wherein the lateral segment of the front portion has a first stiffness, the medial segment of the front portion has a second stiffness, and the first stiffness is greater than the second stiffness; and

wherein the lateral segment of the front portion with the first stiffness comprises a material that extends to the rear portion.

20. The footwear product of claim 19 , wherein the lateral segment of the rear portion is stiffer than the medial segment of the rear portion.
